The rule: one or two imperative sentences ("Do X", "Never Y"), specific enough to change behavior. A platitude ("be careful with tests") fails.
Target file:
- Project lessons (this codebase, its conventions or tooling) go in the instructions file at the root from git rev-parse --show-toplevel: CLAUDE.md in Claude Code, AGENTS.md in Codex. Outside a repository, ask where to write.
- Lessons that apply across projects go in ~/.claude/CLAUDE.md in Claude Code or ~/.codex/AGENTS.md in Codex. In another host, ask which file it reads.
- If the file is a symlink, edit the file it resolves to. If it only imports another file (a line such as @AGENTS.md), edit the imported file.
Overlap: if the rule already exists, stop and say where. If a related rule exists, refine it instead of adding a duplicate.
Approval: show the rule (or the old and new text of a refined rule), the file path, and the section: an existing section that fits, or else a new ## Learned Rules section. Never propose any other new heading. Write nothing until the user approves.
